SSH Access denied after upgrading Gitlab Helm from 13.4.2 to 13.9.7

Hello!

I upgraded my helm chart from 4.4.2 to 4.9.7 (the chart version). I first updated to 4.5.7, then 4.6.7, then 4.7.9, then 4.8.8 and finally to 4.9.7.

Everything was working so far, except that cloning or pulling via SSH is not working anymore. I also tried to generate a new SSH Key and to add it, but the error is still the same.

When I try to do a ssh git@myserver.com -v I get:

debug1: Will attempt key: /Users/username/.ssh/id_rsa RSA SHA256:{...} explicit
debug1: SSH2_MSG_EXT_INFO received
debug1: kex_input_ext_info: server-sig-algs=<ssh-ed25519,ssh-rsa,rsa-sha2-256,rsa-sha2-512,ssh-dss,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521>
debug1: SSH2_MSG_SERVICE_ACCEPT received

debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Next authentication method: keyboard-interactive
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: No more authentication methods to try.

No more background migration tasks are running and I have no idea what to do now. Cloning via HTTPS is working, but I want to have the SSH part running again :slight_smile:

Thanks in advance for any help!

I could isolate that it happens while upgrading from 4.6.7 to 4.7.0.

Has nobody an idea?
